JOHN L. BENTON, OF LOS ANGELES, CALIFORNIA.

PORTABLE SHUTTER-LOCK.

Specification of Letters Patent.

Patented. Jan. 12, 1909.

Application filed. March 18, 1908. Serial No. 421,823.

T all whom it may concern:

Be it known that 1, JOHN L. BENTON, a citizen of the United States, and resident of Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Improvement in Fortable Shutter-Locks, of which the following is a specification.

The object of my invention is to provide a portable shutter lock arranged to detachably connect shutter fastening devices along the inside of the shutters for locking the shutters closed when so desired so that they cannot be opened from the exterior, said lock being adjustable to suit shutters having their fastening devices arranged at different distances from each other.

A practical embodiment of my invention is represented in the accompanying drawings in which Figure 1 is a view showing the outside window shutters closed and my improved portable shutter lock applied thereto, Fig. 2 is a horizontal section taken in the plane of the line A-A of Fig. 1, looking in the direction of the arrows,-Fig. 3 is an enlarged detail side view of the shutter lock, Fig. A is a top plan view of the same, and Fig. 5 is a cross section taken in the plane of the line B-B of Fig. 3, looking in the direction of the arrows.

The outside window shutters are denoted by 1 and 2, each of which shutters is provided with fastening devices comprising an inner hook 3 and an outer hook 4 of well known or approved form. The sill staples which are engaged by the inner hooks 3 for removably holding the shutters closed, are denoted by 5.

My improved lock for engaging the inner hooks of both shutters for locking the shutters closed, is constructed as follows: Two longitudinally adjustable members 6 and 7 are locked and released between two plates 8 and 9 by means of a clamp screw 10 having a suitable operating handle 11. clamping plates are preferably provided with longitudinal recesses arranged opposite each other for receiving the members 6 and 7 and guiding them in their longitudinal adjustments. These members 6 and 7 are provided at their outer ends with hooks 12 and 13 which are arranged to engage the inner hooks 3 of the shutter fastening devices. These hooks 12 and 13 may be passed around the outer sides of the inner hooks 3 or they The said may be passed through holes 14: through the heads of said inner hooks.

In operation, after the shutters have been closed, the shutter lock may be placed in its operative position with the hooks of the members 6 and 7 of the lock engaging the inner hooks of the shutter, the clamping plates 8 and 9 of the lock being first released so that the members may be forced as far inwardly as possible. The clamp screw 10 is then turned in a direction to clamp the members 6 and 7 of the lock against longitudinal movement. It will thus be seen that it is impossible when the lock is in position, for a person on the outside of the shutters to open the shutters or even to move the inner hooks of the shutter fastening devices away from their temporary engagement with their staples.

When it is desired to release the shutters, the clamp screw 10 is unscrewed, thus freeing the adjust-able members 6 and 7 of the lock and permitting them to be moved outwardly a suiiicient distance to disengage their hooks 12 and 13 from the inner hooks of the shutter fastening devices. It will also be seen that these members 6 and 7 may be readily adjusted so that they may be applied to shutters having their shutter fastening devices at a greater or lesser distance apart.

It is evident that various changes might be resorted to in the construction, form and arrangement of the several parts; hence I do not wish to limit myself strictly to the structure herein set forth, but

What I claim is:

1. A portable shutter lock comprising two longitudinally adjustable members arranged to detachably connect the shutter fastening devices and means for locking and releasing the members.

2. A portable shutter lock comprising two longitudinally adjustable members arranged to detachably connect the shutter fastening devices and means for locking and releasing the members comprising clamping plates embracing the members and a clamp screw therefor.

3. A portable shutter look comprising two longitudinally adjustable members having hooks at their outer ends arranged to detachably engage the shutter fastening devices and means for locking and releasing the members.

4:. A portable shutter lock comprising two longitudinally adjustable members having V 2 V a 909,525

hooks at their'outer ends arranged to detachably engage the shutter fastening devices and means for lockin and releasing the members comprising 0 amping plates 5 embracing the members andv a clamp screw therefor. V V

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two Witnesses, this 10th day of March 1908.
